Political reasons have ruled out the dump and reload options, but restoring
the entire database took several hours. I'm also restricted on version
because newer versions of postgres are not supported with that specific
product, including maintenance updates.
So I'm trying to fix things in place which is where some of the difficulty
is coming in. I did test the the restored database on a dev machine, with
vacuum full, alter table, and cluster table all taking a relatively short
window of time.
I'm just trying to get the best method based on the limitations I have been
handed. Right now it seems like clustering the table on an index, then
dropping that cluster flag might be the cleanest way, but I'm just not 100%
sure.
